I brought my new 2019 Silverado RST to the dealer because TPMS was saying service. I also told him about the transmission shudder at sLow speeds.  They said they couldn’t duplicate it. They claimed they have had the problem and on older trucks but not on the 2019.  I’m thinking this is BS.  Anyone had the problem on a 2019 with 8 speed?

I haven't had any shudder and I am over 12000 miles now. Daily driver and tow vehicle (open car trailer)

 

 

I do have the 1-2 slam every once in a while after it sits. 

 

I had several issues with the transmission shifting when I first bought it but the dealer said "no problem found" and did a relearn and that cured most weird shifts.

 

The 8 speed feels great most of the time. No shudder out of mine, yet. no fluid change done yet, either.

For 2019 it all depends on when the truck was produced. I don't remember the exact date but if it was produced before March 1st 2019 (or something very close to that) it didn't have the updated fluid and could have the shudder.

When was the truck built?  There is a break point on the 2019 new body for shudder concern.  Typically you will get the shudder 25-80mph.  It can be quite noticeable too.

I’m having a bad shudder on my 2020 Sierra dually duramax with 10 speed. Delear feels it also and is worse in tow mode. However they say it’s something they never heard of. Trucks now at delear three days and they say could be weeks. Only 8000 miles on it!! Very aggravating!!!

ours started slipping and clunking months ago mainly cold first trip of the day 3-4 slips badly at slow take off cold.

last week put it in reverse backed up like 20 ft stopped for a second  then went to backup again it just sat there with transmission slipping away never moved for 30 seconds i put it park back to reverse and it finally moved again.and of course dealer cannot feel it replicate it or hear the rear end clunk like hell either real convenient

2019 LTZ here.  If I reverse any farther than lets say a parking spot, I lose power for a couple seconds when i put it in drive and then it studders bad. Took it to the dealer and they flushed the trans and put new fluid in it and stated it will go away in 500 miles.  Well it's been 2,000 miles and it still does it. Haven't taken it back to dealer yet.

2019 Sierra SLT 5.3L  8 speed - I had a shudder as well. Aggressive shifts at very low speed. Like coasting up to a stop sign and then pressing the gas pedal to speed up. Sometimes very aggressive. Took it in and they reprogrammed the transmission shift points (thats what they told me) and it is much better. Not totally gone but about 75% better than before.

Does anyone know why the fluid was changed and the fluid was changed from what to what? Thanks.

The original fluid was hydroscopic and the water in the fluid was causing the issues. GM is not the only manufacturer to have this issue.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
